In home network, 4 devices are connected by LAN cables to the router. Router is simple DLink supplied by ISP. I need to know which bandwidth is used at the moment by each of 4 "clients" ("cables").
Some devices are not PCs (tv settop, for example). Or PC not easily accessed physically. So I need to measure bandwidth at central point, not by commands on clients.
The router does not show per-client bandwidth info in web management.
